This LED Digital Voltmeter Panel Meter is a compact and accurate voltage monitoring module designed for real-time DC voltage measurement in electronic, automotive, and solar applications. It features a bright 0.56” LED display for clear readings in various lighting conditions.

The meter supports two measurement modes (0–30V or 0–100V depending on wiring configuration) and requires an external DC power supply (5–30V) for operation. It is widely used in battery systems, power supplies, DIY electronics, and embedded monitoring projects.

⚠️ Important: The measurement signal is NOT the power supply. A separate working voltage must be provided to power the module.

Wiring Instructions

  • Black wire: Common negative (GND)
  • White wire: Positive input of measured voltage
  • Red wire: Positive power supply (5–30V DC working voltage)

Features

  • Wide measurement range: 0–30V / 0–100V (depending on wiring type)
  • Bright 0.56” LED digital display
  • Available display colors: Red / Green / Blue / Orange / White
  • High input impedance (>100KΩ)
  • Low power consumption
  • Fast refresh rate (~300ms)
  • Compact panel-mount design
  • High accuracy voltage monitoring
